JoJo and Winnie are two headstrong sisters with very different ideas about having fun. JoJo wants nothing more than to be left alone so she can read peacefully in her room. Her little sister, Winnie, would give anything to be let into that private world. JoJo may be a bossy know-it-all, but Winnie is a motormouthed copycat -- and an expert at embarrassing JoJo in public. Sisterhood is no picnic! But in spite of their many differences, they both realize that when you really need one, there is no better friend than a sister.
